Arenado has struggled offensively since the All-Star Break, leading to the Cardinals selling at the deadline. He has a .159 batting average and .417 OPS in 12 games since the break. The Redbirds are just 3-9 in those games, knocking them further back in the playoff race.

However, he wasn't dealt and remained in St. Louis. But, the next day, as Katie Woo of The Athletic reports, the Cardinals are losing Arenado to the injured list with a shoulder issue. He'll go on the 10-day injured list, as Nolan Gorman is activated in his place.

The Cardinals are expected to place Nolan Arenado on the 10-day IL (shoulder) prior to Friday's game, The Athletic's Katie Woo is reporting.
